Chapter A. Introduction

When performing a FE calculation of a structure, the modeling assumptions as well as the objectives must be defined. Those goals generally consist of solving:

the displacements caused by a static loading (permanent) quasi-static (without inertial effects) or dynamic (fast-loading,)
internal state, such as stresses, damages inflicted (cracking, etc.)

Among the modeling hypotheses, it is preferable to handle chronologically:

the choice of the general formulation,
the dimensionality of the model,
the choice of the elements,
the definition of the interactions with the environment.
